Introduction: Jeff-A Cheap and Simple Ic Robot

About: failure keeps you going. that's what some people say, I say custard creams keep you going. woundnt get though a project with out them

Jeff took 5 weeks to compete and is a simple IC robot. Jeff's main thing is the led headlights witch come on automatically when it is dark. It works by having what is called a current see sore witch when the current is higher on the Ldrs side compare to the Variable resistors side it puts power to chip (Ua741) then puts power to the transistor (BC109)  then to the Leds. Jeff is simple to make but fiddle as you can see he is made from a sandwitch tub,If you what instructions please leave a comment below.
